I had great results running mostly TB-500 (also some BPC 456) to clear up my tennis elbow on both arms a little over a year ago. I injected into the sore area (bilaterally each time) and could see immediate reduction in skin redness near the inject site. It took the better part of a couple months for the soreness to go away completely, but it has not come back (other than an occasional small flare up that is easily managed) in the year plus since. I did the maintenance for a couple months after the soreness went away, but then decided to hold onto some product for future treatments, that haven't been necessary.
Good luck and keep us posted.
